Instant accomplishment.
For going from 18 to roughly 274 seconds, you did an unparalleled job. I like how the twists and beats on top of trancifying(is that a word?) the original melody simply contributed to a better song. It's heart came from Sonic, but I see this song in a Megaman game for some reason. XD
If anybody could do better, I'll shit bricks. Nice work!
